+    <p>The <code>event-focus</code> module supplies a behavior patch for the native
+    <code>focus</code> and <code>blur</code> events to allow them to bubble for event delegation.</p>
+</div>
+
+<h2 id="bubble-time">Bubble time</h2>
+
+<p>Most DOM events bubble.  If, for example, you click on a button in a form,
+the click event will be dispatched to event subscribers on the button, on the
+fieldset, on the form, on the div containing the form, and so on up to the
+<code>document</code>.  You can subscribe to the click event at any level and your
+callback will be executed.  But <code>focus</code> and <code>blur</code> aren't like that.  They are
+only dispatched to subscribers on the element that received or lost focus.</p>
+
+<p>But <a href="delegation.html">we like event delegation</a> so we determined
+a way to synthesize bubbling for <code>focus</code> and <code>blur</code> using <a
+href="http://www.w3.org/TR/DOM-Level-3-Events/#event-flow">capture phase</a>
+subscriptions in non-IE browsers, and proprietary focus-related events in IE
+that do bubble.  The result should be transparent for individual element
+<code>focus</code> and <code>blur</code> subscriptions, but make <code>focus</code> and <code>blur</code> work as you would
+expect when subscribing higher in the document tree.</p>

+    &lt;li&gt;But by default none of those &#x60;focus&#x60; events will report to #items&lt;&#x2F;li&gt;
